Paul Copioli has a reputation beyond repute

Facts

We have used the window motors for 3 of the past 4 years and in every case they did not back drive.

1. 2000 used as our winch motor and hung after the power was shut off

2. 2001 used as our conveyor extender motor and held 200 lbs of pre-load without back driving

3. 2003 used as one our strap motor and one as our bin lift motor. Neither were backdriven. The bin lift motor held me up (180 lbs) when it was shut off.

This year we will be using the window motors for an application that requires them to hold position while turned off.
